MODE FOR THE INVENTION

Hereinafter, various embodiments of the present specification will be described with reference to the accompanying drawings. However, it should be understood that there is no intent to limit the present disclosure to the particular forms disclosed herein; rather, the present disclosure should be construed to cover various modifications, equivalents, and/or alternatives of embodiments of the present disclosure. In describing the drawings, similar reference numerals may be used to designate similar constituent elements.

As used herein, the expression “have”, “may have”, “include”, or “may include” refers to the existence of a corresponding feature (e.g., numeral, function, operation, or constituent element such as component), and does not exclude one or more additional features.

In the present disclosure, the expression “A or B”, “at least one of A or/and B”, or “one or more of A or/and B” may include all possible combinations of the items listed. For example, the expression “A or B”, “at least one of A and B”, or “at least one of A or B” refers to all of (1) including at least one A, (2) including at least one B, or (3) including all of at least one A and at least one B.

The expression “a first”, “a second”, “the first”, or “the second” used in various embodiments of the present disclosure may modify various components regardless of the order and/or the importance but does not limit the corresponding components. For example, a first user device and a second user device indicate different user devices although both of them are user devices. For example, a first element may be termed a second element, and similarly, a second element may be termed a first element without departing from the scope of the present disclosure.

It should be understood that when an element (e.g., first element) is referred to as being (operatively or communicatively) “connected,” or “coupled,” to another element (e.g., second element), it may be directly connected or coupled directly to the other element or any other element (e.g., third element) may be interposer between them. In contrast, it may be understood that when an element (e.g., first element) is referred to as being “directly connected,” or “directly coupled” to another element (second element), there are no element (e.g., third element) interposed between them.

The expression “configured to” used in the present disclosure may be exchanged with, for example, “suitable for”, “having the capacity to”, “designed to”, “adapted to”, “made to”, or “capable of” according to the situation. The term “configured to” may not necessarily imply “specifically designed to” in hardware. Alternatively, in some situations, the expression “device configured to” may mean that the device, together with other devices or components, “is able to”. For example, the phrase “processor adapted (or configured) to perform A, B, and C” may mean a dedicated processor (e.g. embedded processor) only for performing the corresponding operations or a generic-purpose processor (e.g., central processing unit (CPU) or application processor (AP)) that can perform the corresponding operations by executing one or more software programs stored in a memory device.

The terms used in the present disclosure are only used to describe specific embodiments, and are not intended to limit the present disclosure. As used herein, singular forms may include plural forms as well unless the context clearly indicates otherwise.

FIG. 5A is a block diagram illustrating elements of a processor 120 according to an embodiment of the present invention. According to an embodiment, the processor 120 may include an authentication approval unit 121, an identification information provider 123, and a device account manager 125, all of which may be formed of a single integrated module but, in this embodiment, may be formed as separate components.

According to an embodiment, the authentication approval unit 121 may control the display 160 to display an authentication request message received from the device account server 108. Simultaneously or sequentially, the authentication approval unit 121 may store the received authentication request message in the memory 130. If an input signal for authentication approval is received from a user, the authentication approval unit 121 may transmit authentication approval information to the device account server 108.

According to another embodiment, the authentication approval unit 121 may perform an authentication approval operation by using authentication information created automatically on the basis of conditions predetermined in the electronic device 101.

The authentication approval unit 121 may receive such predetermined conditions from a user and store the received conditions in the memory 130.

According to an embodiment, the identification information provider 123 may offer identification information to the external device 107. For example, the identification information provider 123 may recognize a distance between the electronic device 101 and the external device 107. If the recognized distance is equal to or smaller than a predetermined distance, the identification information provider 123 may retrieve identification information from the memory 130 and then transmit it to the external device 107. The identification information provider 123 may receive proximity information between the electronic device and the external device 107 from the communication interface 170 or the sensor module 240. Then the identification information provider 123 may compare the received proximity information with a predetermined distance. This predetermined distance may be, for example, the minimum or maximum distance value in specification which allows the communication interface 170 can transmit data to the external device 107. Also, a predetermined distance may be an arbitrary value which can be set by a user. If a distance between the electronic device 101 and the external device 107 is equal to or smaller than a predetermined distance, the identification information provider 123 may transmit identification information to the external device 107 through the communication interface 170. Therefore, the external device 107 may not receive a user's input for authentication. The external device 107 may recognize, as information for an authentication approval request, identification information received from the electronic device 101.

According to an embodiment, the device account manager 125 may manage at least one external device 107 authenticated successfully and an authentication status (e.g., authentication access/release) of at least one service offered through the external device 107 or the electronic device 101.

According to an embodiment, at operation 610, the electronic device 101 may register identification information in the device account server 108. For example, the electronic device 101 may transmit user authentication request information therefor to the device account server 108. This authentication request information may include user identification information of the electronic device 101 and device information of the electronic device 101. The device account server 108 may store the authentication request information received from the electronic device 101. At this operation, the electronic device 101 may be registered as a device that supports user authentication for the external device 107, a service offered through the external device 107, or a service offered through the electronic device 101.

According to an embodiment, at operation 630, the electronic device 101 may receive an authentication request message based on identification information from the device account server 108.

According to an embodiment, the authentication request message may be a message for requesting user authentication for a device or service, which may be, for example, the external device 107, a service offered through the external device 107, or a service offered through the electronic device 101.

According to an embodiment, the external device 107 may receive an input of a user authentication request therefor or for a service offered therethrough from a user. For example, the external device 107 may receive user identification information of the electronic device 101, as an authentication request input, from a user. Also, the external device 107 may transmit authentication request information therefor or for a service offered therethrough to the device account server 108. The device account server 108 receiving the authentication request information from the external device 107 may search a device profile manager 108 b for device information of the electronic device 101 corresponding to user identification information. The user identification information may be contained in the authentication request information transmitted to the device account server 108 by the external device 107. If any device information of the electronic device 101 corresponding to the user identification information is found in the device profile manager 108 b, the device account server 108 may transmit an authentication request message to the electronic device 101, based on a phone number, etc. contained in the device information of the electronic device 101. Also, the device account server 108 may transmit the authentication request message to the electronic device 101 by using a push message, and for implementing this, may include an additional push server or the like.

According to another embodiment, the electronic device 101 may receive an input for a user authentication request for a service offered therethrough from a user. Then the electronic device 101 may transmit user authentication request information for a service offered therethrough to the device account server 108. For example, the user authentication request information may include user identification information of the electronic device 101 and device information of the electronic device 101. The device account server 108 receiving the authentication request information from the electronic device 101 may search the device profile manager 108 b for device information of the electronic device 101 corresponding to user identification information. If any device information of the electronic device 101 corresponding to the user identification information is found in the device profile manager 108 b, the device account server 108 may transmit an authentication request message to the electronic device 101. The authentication method according to this embodiment may not use the external device 107.

According to an embodiment, the electronic device 101 may display, through the display 160, the authentication request message received from the device account server 108. For example, the authentication approval unit 121 may recognize that the authentication request message is received from the device account server 108. Then the authentication approval unit 121 may transmit authentication request message information to the display 160 and control the display 160 to display the authentication request message information thereon.

According to an embodiment, at operation 650, the electronic device 101 may receive an input for a user authentication approval of a device or service from a user. This device or server may be the external device 107, a service offered through the external device 107, or a service offered through the electronic device 101. For example, the authentication approval unit 121 may receive an input signal regarding authentication approval or not of such a device or service from a user through the input/output interface 150 or the display 160.

According to an embodiment, at operation 670, the electronic device 101 may transmit authentication approval information to the device account server 108 so that user authentication for a device or service is completed through the device account server 108. For example, when an input for authentication approval is received from a user, the authentication approval unit 121 may create authentication approval information and then transmit the authentication approval information to the device account server 108 through the communication interface 170.

According to an embodiment, depending on the authentication approval information received from the electronic device 101, the device account server 108 may transmit device authentication token information and/or service authentication token information to the external device 107 or the electronic device 101. Based on such device authentication token information and/or service authentication token information, the external device 107 or the electronic device 101 may finish user authentication for the external device 107, the electronic device 101, a service offered through the external device 107, or a service offered through the electronic device 101. Although not shown, according to another embodiment, in case each of the electronic device 101 and the external device 107 has a phone number (i.e., user identification information), this operation of user authentication may be performed at the external device 107 or at the electronic device 101. For example, in case of trying to further authenticate another service after user authentication for a certain device or for a service offered through the device, it is possible to create user authentication request information by entering user identification information of the external device 107 or user identification information of the electronic device 101. Also, according to another embodiment, the electronic device 101 may offer a user registration menu to a user, and the user may enter a phone number of the external device 107 into the user registration menu. This user registration menu may be a menu capable of using, as user identification information, both a phone number of the electronic device 101 and a phone number of the external device 107. Therefore, a user of the electronic device 101 may use both phone numbers as user identification information required for user authentication. Additionally, each of the external device 107 and the electronic device 101 may be a means for entering user authentication approval information.

FIGS. 6B to 6D are exemplary diagrams illustrating operations shown in FIG. 6A.

FIG. 6B illustrates operation of requesting user authentication for an account service 601 offered through the external device 107 (e.g., PC). A user may enter user identification information “010-2716-XXXX” into a user identification information input window 602 of the external device 107. After that, a user may click a login button 603, and then the external device 107 may create user authentication request information for the account service 601 in response to the click on the login button 603. The user authentication request information may include information about the account service 601 offered through the external device 107 and user identification information. Although not shown, the external device 107 may transmit created authentication request information to the device account server 108. Then the device account server 108 may search the device profile manager 108 b for the electronic device 101 mapped to user identification information.

Then the electronic device 101 may create authentication approval information for the account service and transmit the created authentication approval information to the device account server 108. On the other hand, if a user selects a cancel button 606 in the authentication request message 604, the electronic device 101 may recognize this selection as an input for denying authentication approval. Then the electronic device 101 may take no action in response to this input.

FIG. 6D illustrates operation of requesting user authentication for a kids account creation service 607 and a content purchase service 608. The kids account creation service 607 and the content purchase service 608 may be different from each other. In this operation, a user of the external device 107 (e.g., PC) may be a kid. The user may enter user identification information “010-1234-XXXX” into a user identification information input window 607 a or 607 b of the external device 107. At this time, the user identification information may be identification information about a user's parent. After entering the user identification information, the user of the external device 107 may select (e.g., touch or click) a login button 607 b, and then the external device 107 may create user authentication request information for the kids account creation service 607. Similarly, the user who enters the user identification information may select a content purchase button 608 b, and then the external device 107 may create user authentication request information for the content purchase service 608. The external device 107 may transmit the created user authentication request information to the device account server 108, and then the device account server 108 may transmit an authentication request message to a user (or a user's parent) of the electronic device 101 mapped to the user identification information. When the user (or the user's parent) of the electronic device 101 approves authentication, user authentication for each service may be finished.

FIG. 7A is a flow diagram illustrating operations of, at an electronic device, offering user identification information to an external device according to an embodiment of the present invention. FIGS. 7B and 7C are exemplary diagrams illustrating operations shown in FIG. 7A. In the following description with reference to FIGS. 7A to 7C, some operations similar to those of FIGS. 6A to 6D may be omitted.

According to an embodiment, at operation 710, the electronic device 101 may check whether a distance between the electronic device 101 and the external device 107 is equal to or smaller than a predetermined distance. For this, the identification information provider 123 may measure, in real time or periodically, a distance between the electronic device 101 and the external device 107 by using the communication interface 170 or the sensor module 240. Then the identification information provider 123 may determine whether the measured distance is equal to or smaller than a predetermined distance. For this, the identification information provider 123 may receive a value of the predetermined distance from the memory 130. The predetermined distance value may be, for example, certain proximity information which is set by a user or registered by a designer of the electronic device 101. According to another embodiment, the predetermined distance value may be the minimum or maximum functional distance which allows the Bluetooth module, the NFC module, etc. of the communication interface 170 can transmit or receive data.

According to another embodiment, if a distance between the electronic device 101 and the external device 107 is equal to or smaller than a predetermined distance, the electronic device 101 may offer identification information thereof to the external device 107 at operation 720. For example, when a distance between the electronic device 101 and the external device 107 is equal to or smaller than a predetermined distance, the identification information provider 123 may transmit identification information to the external device 107. Referring to FIG. 7B, for example, the external device 107 is requesting an input of identification information (e.g., user identification information of the electronic device 101) for user authentication for a service (or account) offered therethrough. If a distance between the electronic device 101 and the external device 107 is equal to or smaller than a predetermined distance, the external device 107 may receive user identification information from the electronic device 101 and display the received information in a user identification information input window 701. The user identification information may be, for example, a phone number (e.g., 010-2716-XXXX) of a user of the electronic device 101. A user may check the phone number displayed in the user identification information input window 701 and select a login button 702. Then the external device 107 may recognize this selection of the login button 702 as a login input.

According to another embodiment, from the electronic device 101, the external device 107 may receive an input of the user identification information in the window 701 and further receive a login input for the button 702.

According to still another embodiment for offering user identification information, as shown in FIG. 7C, the external device 107 is requesting an input of identification information (e.g., user identification information of the electronic device 101) for user authentication for a service offered therethrough. Contrary to FIG. 7B, the external device 107 requests a selection of user accounts 703 and 704 authenticated in a service thereof. These user accounts 703 and 704 which have been authenticated through the electronic device 101 may be stored in the memory of the external device 107. Although not shown, the user accounts 703 and 704 may appear in the form of a popup window when a specific event such as a double click occurs on the user identification information input window 701 in FIG. 7B. If a distance between the electronic device 101 and the external device 107 is equal to or smaller than a predetermined distance, the electronic device 101 may transmit control information to the external device 107 so that the user account 703 for a user of the electronic device 101 may be distinctively displayed on the external device 107. Also, the external device 107 may recognize the electronic device 101 and thereby recognize specific identification information stored therein. For example, if a distance between the electronic device 101 and the external device 107 is equal to or smaller than a predetermined distance, the external device 107 may recognize the electronic device 101 and retrieve the user account 703 mapped to the electronic device 101 from the memory thereof. If the user account 703 mapped to the electronic device 101 is found in the memory, the external device 107 may distinctively display the user account 703 based on user identification information of the electronic device 101. When the user account 703 is selected, a user may select (e.g., touch or click) a login button 705. Alternatively, when the user account 703 of the electronic device 101 is found, the external device 107 may automatically transmit authentication request information having the user account 703 to the device account server 108.

Returning to FIG. 7A, according to an embodiment, if a distance between the electronic device 101 and the external device 107 exceeds a predetermined distance, the external device 107 may not receive identification information from the electronic device 101 at operation 730. Instead, the external device 107 may receive an input of identification information directly from a user.

According to an embodiment, at operation 740, the electronic device 101 may receive an authentication request message from the device account server 108, based on identification information.

According to an embodiment, at operation 750, the electronic device 101 may receive an input signal for service authentication approval of the external device 107.

According to an embodiment, at operation 760, the electronic device 101 may transmit authentication approval information to the device account server 108 so that user authentication for a service offered at the external device 107 is completed through the device account server 108. The device account server 108 may create authentication token information, based on authentication approval information, and transmit it to the external device 107. Therefore, service authentication may be finished at the external device 107.

FIG. 7D is an exemplary diagram illustrating operations of, at an electronic device 101 and a device account server 108, performing authentication for additional electronic devices according to various embodiments of the present invention.

As shown in FIG. 7D, the electronic device 101 may offer identification information (e.g., an access key, etc.) for recognizing the electronic device 101 or a user thereof to at least one of additional electronic devices 719, 721, 723 and 725. Then the at least one of additional electronic devices 719, 721, 723 and 725 may deliver, without any input, the received identification information to a server (e.g., the device account server 108) having authentication information of the electronic device 101. This server may determine whether the identification information correspond to the electronic device 101 or a user of the electronic device 101, and then, based on such information, request the electronic device 101 to authenticate the at least one of additional electronic devices 719, 721, 723 and 725. If this authentication request is approved by the electronic device 101, authentication for the at least one additional electronic devices 719, 721, 723 and 725 may be completed. In this case, if the electronic device 101 is a parent terminal, at least one of the additional electronic devices 719, 721, 723 and 725 may be authenticated as a child terminal of the parent terminal or of a user of the parent terminal.

Now, focusing on FIG. 7D, the entire authentication method is described. At operation 707, the electronic device 101 may perform, together with the device account server 108, initial authentication associated with the electronic device 101 or a user of the electronic device 101. For example, the electronic device 101 may register identification information thereof or user identification information thereof in the device account server 108. Thereafter, according to various embodiments discussed hereinbefore, the electronic device 101, the external device 107 and the device account server 108 may perform authentication for the external device 107 at operations 709, 711 and 713.

Additionally, the electronic device 101 and the device account server 108 may perform authentication for at least one of the additional electronic devices 719, 721, 723 and 725. Specifically, at operation 715, the electronic device 101 may deliver identification information to a certain additional electronic device that needs authentication or login. This identification information may be information for identifying the electronic device 101 or a user of the electronic device 101. For example, this identification information may include identification information of the electronic device 101, user identification information of the electronic device 101, and/or an access key which can be created dynamically. If the electronic device 101 offers such identification information to the external device 107 or the additional electronic device through short range communication or a user's input, the additional electronic device may transmit an authentication/login request including identification information to the device account server 108 at operation 717. Then the device account server 108 may identify the electronic device 101 mapped to the received identification information and also, at operation 711, request the identified electronic device 101 to authenticate the additional electronic device. The electronic device 101 may approve authentication for the additional electronic device in response to a request received from the device account server 108 and also, at operation 713, transmit authentication approval information to the device account server 108.

FIG. 8A is a flow diagram illustrating operations of, at an electronic device 101, offering an access release control signal to an external device 107 according to an embodiment of the present invention. FIG. 8B is an exemplary diagram illustrating operations shown in FIG. 8A. In the following description with reference to FIGS. 8A and 8B, some operations similar to those of FIGS. 6A to 6D may be omitted.

According to an embodiment, at operation 810, the electronic device may receive an authentication request message from the device account server 108, based on identification information.

According to an embodiment, at operation 830, the electronic device 101 may receive an input signal for user authentication approval of a service offered through the external device 107 based on authentication request information.

According to an embodiment, at operation 850, the electronic device 101 may transmit authentication approval information to the device account server 108 so that user authentication for a service offered at the external device 107 is completed through the device account server 108. Therefore, user authentication for a service may be finished at the external device 107.

According to an embodiment, at operation 870, the electronic device 101 may determine whether a distance between the electronic device 101 and the external device 107 exceeds a predetermined distance. For this, the device account manager 125 may measure, in real time or periodically, a distance between the electronic device 101 and the external device 107 by using the communication interface 170 or the sensor module 240. Then the device account manager 125 may determine whether the measured distance exceeds a predetermined distance. For this, the device account manager 125 may retrieve a stored predetermined distance from the memory 130. The predetermined distance value may be, for example, certain proximity information which is set by a user or registered by a designer of the electronic device 101. According to another embodiment, the predetermined distance value may be the minimum or maximum functional distance which allows the Bluetooth module, the NFC module, etc. of the communication interface 170 can transmit or receive data.

According to an embodiment, if the measured distance exceeds a predetermined distance, the electronic device 101 may transmit, at operation 890, a control signal to the external device 107 so as to release access of a service offered through the external device 107. For example, the electronic device 101 may transmit a control signal to the external device 107 so that an account based on user identification information of the electronic device 101 may be logged out in a service offered through the external device 107. Also, the external device 107 may recognize a distance from the electronic device 101 and, if this distance exceeds a predetermined distance, may log out a specific account authenticated through the electronic device 101. This predetermined distance may be stored in the external device 107 or received from the electronic device 101.

For example, as shown in FIG. 8B, a smart TV which is the external device 107 may display a plurality of user accounts 801, 802 and 803 each of which completes user authentication for a service. The external device 107 may display a user account 801, authenticated through the electronic device 101, so as to be distinct from the other user accounts 802 and 803. For example, an account which is accessing a current service is the USER A 801. If a plurality of user accounts 801, 802 and 803 are accounts authenticated using user identification information of the same electronic device 101, the currently accessed user account 801 may be an account which completes the latest authentication.

According to an embodiment, if a distance between the external device 107 and the electronic device 101 exceeds a predetermined distance, the electronic device 101 may transmit, to the external device 107, a control signal for instructing logout of the USER A 801 account in a corresponding service. Also, the external device 107 may recognize a distance from the electronic device 101 and, if this distance exceeds a predetermined distance, may log out the user account 801 authenticated through the electronic device 101 (or authenticated most recently).

The device profile manager by devices 109 a contains authenticated services classified according to authenticated devices, and the device profile manager by services 109 b contains authenticated devices classified according to authenticated services. The device account server 108 may store information received from the electronic device 101 or the external device 107 in the device profile manager 108 b. Although FIG. 9 depicts the device profile manager by devices 109 a and the device profile manager by services 109 b separately, this is exemplary only. Alternatively, the device account server 108 may classify all types of information according to devices and services in a single device profile manager 108 b.

FIG. 10A is a flow diagram illustrating a process of, at a device account server, performing authentication for a service requested by an electronic device according to an embodiment of the present invention. In the following description with reference to FIG. 10A, some operations similar to those of FIG. 6A may be omitted.

According to an embodiment, at operation 1010, the device account server 108 may receive authentication request information for a service offered through the electronic device 101. The device account server 108 may receive, as a precondition to user authentication operation for a device or service, initial authentication request information from the electronic device 101. For example, the device account server 108 may receive, from the electronic device 101, user identification information of the electronic device 101, device information of the electronic device 101, and/or service information offered through the electronic device 101.

According to an embodiment, at operation 1030, the device account server 108 may store, in the device profile manager 108 b, service information of the electronic device 101 mapped to device information of the electronic device 101, based on user identification information of the electronic device 101.

According to an embodiment, at operation 1050, the device account server 108 may create authentication token information for the electronic device 101 and for a service offered at the electronic device 101, and also transmit the created authentication token information to the electronic device 101. Then the electronic device 101 may store the authentication token information received from the device account server 108 in the memory 130.

FIG. 10B is an exemplary diagram illustrating a process of updating a device profile manager 108 b of a device account server 108 according to operations shown in FIG. 10A. Although FIG. 10B illustrates an update process of the device profile manager by devices 109 a, this is exemplary only. The same update process may be applied to the device profile manager by services 109 b.

According to an embodiment, the device account server 108 may store authentication request information, received from the electronic device 101, in the device profile manager 108 b. The authentication request information may include at least one of user identification information 1001, device information 1002 of the electronic device 101, and service information 1003 offered through the electronic device 101. For example, the device account server 108 may store, in the device profile manager by devices 109 a, at least one of the user identification information 1001, the device information 1002 of the electronic device 101, and the service information 1003 offered through the electronic device 101. The device information 1002 may contain a UI item (e.g., representing a mobile phone) and model name (e.g., SHW-M250S). The service information 1003 may contain a message service (e.g., “Chat On”).

FIG. 11A is a flow diagram illustrating a process of, at a device account server, performing user authentication for a device or a service according to an embodiment of the present invention. In the following description with reference to FIG. 11A, some operations similar to those of FIG. 6A may be omitted.

According to an embodiment, at operation 1110, the device account server 108 may receive user authentication request information for a service offered at a specific device. For example, the device account server 108 may receive user authentication information from a service offered through the electronic device 101 and/or a service offered through the external device 107.

According to an embodiment, at operation 1120, the device account server 108 may determine whether a device for offering a service is registered in the device account server 108. For example, authentication request information may contain information about whether a device that requests user authentication for a specific service has or not device authentication token information. If a device has device authentication token information, the device account server 108 may transmit, at operation 1180, service authentication token information to a device that offers a corresponding service. Therefore, a user may simply finish user authentication for the service without a need to pass through an additional authentication process.

According to various embodiments, even though it is determined at operation 1120 that a device is registered in the device account server 108, the device account server 108 may perform operation 1180 or 1150 depending on additional conditions (e.g., a predetermined condition). For example, such a predetermined condition may depend on a service policy or a user's selection. For example, depending on a service policy or a user's selection, the device account server 108 may transmit authentication token information automatically or after authentication approval through the electronic device 101. Therefore, even though a certain device is a device registered in the device account server 108, the device account server 108 may offer the authentication token information to the device or service automatically or by means of authentication through the electronic device 101, depending on whether additional conditions are satisfied, or. If a certain device is a device registered in the device account server 108, and if a predetermined condition is satisfied, the device account server 108 may perform operation 1180. If a certain device is a device registered in the device account server 108, and if a predetermined condition is not satisfied, the device account server 108 may transmit, at operation 1150, an authentication request message for the device to the electronic device 101.

According another embodiment, if a certain device is not a device registered in the device account server 108, the device account server 108 may further determine, at operation 1130, whether to register the device in the device account server 108. For example, the device account server 108 may display authentication-requested service information and device information of a device for offering the service. Also, a user may identify the displayed device information and determine whether to register the device in the device account server 108. For example, if a device is a public PC or the like, a user may not register such a device in the device account server 108.

According to an embodiment, if a user's input for not registering a certain device in the device account server 108 is received, the device account server 108 may transmit an authentication request message to the electronic device 101 at operation 1150. In this case, the authentication request message may be a message that requests user authentication for a service at a corresponding device. Although not shown, if user authentication for a certain service is completed, the device account server 108 may transmit service authentication token information only to a corresponding device.

According to another embodiment, if a user's input for registering a certain device in the device account server 108 is received, the device account server 108 may transmit device authentication token information to the device at operation 1140.

According to an embodiment, at operation 1160, the device account server 108 may determine whether a certain service is registered in the device account server 108. For example, authentication request information may contain information about whether a device that requests user authentication has or not service authentication token information about a corresponding service. If the device has service authentication token information about the service, the device account server 108 may transmit, at operation 1180, service authentication token information to a device that offers the service. Therefore, a user may simply finish user authentication for the service without a need to pass through an additional authentication process.

According to various embodiments, even though it is determined at operation 1160 that a service is registered in the device account server 108, the device account server 108 may perform operation 1180 or 1170 depending on additional conditions (e.g., a predetermined condition). For example, if a re-login request is transmitted to the device account server 108 on the basis of identification information after logout of a specific service at the external device, the device account server 108 may transmit authentication token information automatically or after authentication approval through the electronic device 101, based on a predetermined condition such as a service policy or a user's selection (e.g., whether login information such as ID and password is registered at initial login, etc.). Therefore, even though a certain service is a service registered in the device account server 108, the device account server 108 may offer the authentication token information for the service to a corresponding device automatically or by means of authentication through the electronic device 101, depending on whether additional conditions are satisfied. If a certain service is a service registered in the device account server 108, and if a predetermined condition is satisfied, the device account server 108 may perform operation 1180. If a certain service is a service registered in the device account server 108, and if a predetermined condition is not satisfied, the device account server 108 may transmit, at operation 1170, an authentication request message for the service to the electronic device 101.

According to another embodiment, if a certain device fails to have service authentication token information about a corresponding service, the device account server 108 may transmit an authentication request message for user authentication of the service to the electronic device 101 at operation 1170. Although not shown, when user authentication for the service is completed, the device account server 108 may transmit service authentication token information only to the device.

According to an embodiment, at operation 1190, the device account server 108 may update information stored in the device profile manager 108 b.

FIGS. 11B to 11E are exemplary diagrams illustrating a process of updating a device profile manager 108 b of a device account server according to operations shown in FIG. 11A.

According to an embodiment, FIG. 11B illustrates the device profile manager by devices 109 a updated when user authentication for other service is completed at the authenticated electronic device 101 in FIG. 10B. As shown, device information 1103 and service information 1107 and 1109 may be stored in the device profile manager by devices 109 a, based on user identification information 1101 of the electronic device 101. All kinds of service information 1107 and 1109 may be classified according to the device information 1103.

For example, the device account server 108 may add new service information 1109 to the device profile manager by devices 109 a when user authentication for another service is completed at the same device. The added service information 1109 may be a so-called S Health service used for managing user's health data.

According to an embodiment, FIG. 11C illustrates the device profile manager by devices 109 a updated when user authentication for a service 1109 is completed at the external device 1105 (e.g., PC). The service 1109 offered through the external device 1105 may be a service of the same S Health as the service 1109 offered through the electronic device 101. For example, a user of the electronic device 101 may desire that the S Health service for which user authentication has been completed at the electronic device 101 would be authenticated and used at another device. Therefore, when user authentication for the S Health service is finished at the external device 1105, the device account server 108 may add the external device 1005 and a corresponding service 1109 as shown in FIG. 11C.

According to an embodiment, FIG. 11D illustrates the device profile manager by devices 109 a updated when user authentication for another service 1111 is completed at the external device 1105 (e.g., PC). This service 1111 offered through the external device 1105 may be different from the previously stored services 1107 and 1109. For example, this service 1111 may be the Drop Box service that offers a web file sharing and interworking service. When user authentication for another service 1111 offered through the external device 1105 is finished, the device account server 108 may add this service 1111 into the device profile manager by devices 109 a by mapping the service 1111 to the external device 1105.

According to an embodiment, FIG. 11E illustrates the device profile manager by services 109 b of the device account server 108. The device profile manager by services 109 b may be implemented in another storage space different from that of the device profile manager by devices 109 a. This is, however, exemplary only. Alternatively, the device account server 108 may retrieve information stored in the device profile manager by devices 109 a and then create or reclassify the device profile manager by services 109 b. As shown, the device account server 108 may classify the devices 1103 and 1105 according to services 1107, 1109 and 1111, based on the user identification information 1101.

The above-discussed embodiments of the device profile manager 108 b are exemplary only and not to be considered as a limitation. In another embodiment, the device account server 108 may merely store the device profile manager 108 b without classification by device or service. For example, as shown in FIG. 13B to be discussed later, the device account server 108 may implement the device profile manager 108 b in the form of displaying all of authenticated devices and services.

FIG. 12A is a flow diagram illustrating a process of, at an electronic device 101, controlling a device or a service through a device account server 108 according to an embodiment of the present invention.

According to an embodiment, at operation 1210, the electronic device 101 may receive information about the device profile manager 108 b from the device account server 108. For example, in response to a user's request, the device account manager 125 may request the device account server 108 to offer information having at least one device or at least one service stored in the device profile manager 108 b.

According to an embodiment, the device account manager 125 may create a control input screen for a device or service, based on the device profile manager information received from the device account server 108. In this operation, the device account manager 125 may process the device profile manager information received from the device account server 108. For example, it is possible to resort service information classified according to devices or device information classified according to services or to form such information by means of image items. Additionally, the device account manager 125 may create UI items such as a user account access/release control window so as to receive, from a user, a user account access/release signal for a device or service stored in the device profile manager 108 b. User account access/release may mean that a user's account using a user-authenticated device or service is logged in/out at that device or service.

According to an embodiment, at operation 1230, the electronic device 101 may receive a user account access/release control input for an authenticated device or service from a user. The authenticated device or service may a device or service stored in the device profile manager 108 b. The device account manager 125 may receive a user account access/release control input for the authenticated device or service from a user through the display 160 and then create a user account access/release control signal.

According to an embodiment, at operation 1250, the electronic device 101 may transmit a control signal to the device account server 108. This control signal may include a user account access/release control signal created by the device account manager 125. Based on the control signal received from the electronic device 101, the device account server 108 may transmit the user account access/release control signal to a corresponding device stored in the device profile manager 108 b. The device which receives the user account access/release control signal from the device account server 108 may log out a user account which is in an access state to a certain service. Also, the device which receives the user account access/release control signal from the device account server 108 may log in again a user account which is logged out from the service. Therefore, a user can stop offering a service to a desired device among a plurality of devices sharing the same service with each other.

According to various embodiments, a user may be offered the same message service (e.g., Chat-On, etc.) at both a mobile phone (i.e., the electronic device 101) and a PC (i.e., the external device 107). Information about the mobile phone, PC and message service may be stored for each user in the device profile manager 108 b of the device account server 108. A user may desire to use the message service at only the mobile phone. In this case, the user may request, through a control screen of the mobile phone, the device account server 108 to stop offering the message service at the PC. In response to a user's request, the device account server 108 may transmit a user account logout signal of the message service to the PC. Therefore, the user can use the message service at only the mobile phone.

FIGS. 12B and 12C are exemplary diagrams illustrating operations shown in FIG. 12A.

According to an embodiment, as shown in FIG. 12B, the electronic device 101 may display a device/service control window 1200 having device profile manager information through the display 160. The device/service control window 1200 may contain a user identification information window 1201, device information 1203 or 1205, a more view icon 1208 or 1211, and a device access control item 1207 or 1209. For example, the device access control item 1207 associated with the first device (e.g., SMART PHONE 1) indicates the “ON” state. This means that user account access to services offered through the first device (e.g., SMART PHONE 1) is maintained. Also, the device access control item 1209 associated with the second device (e.g., PC 1) indicates the “OFF” state. This means that user account access to services offered through the second device (e.g., PC 1) is released. The electronic device 101 may receive an input event for the device access control item 1207 or 1209 from a user and then transmit a control signal created in response to the input event to the device account server 108. Therefore, with regard to each individual device, a user of the electronic device 101 may control user access/release for services of the device stored in the device profile manager 180 b.

According to an embodiment, as shown in FIG. 12C, when the more view icon 1208 shown in FIG. 12B is selected by a user, the electronic device 101 may display a user access status of each service 1215 or 1217 in the first device (e.g., SMART PHONE 1). Further, the electronic device 101 may display an information window 1213 for indicating that the displayed services 1215 and 1217 belong to the first device (e.g., SMART PHONE 1). Also, the electronic device 101 may display a cancel window 1223 and, when an input event for selecting the cancel window 1223 is received from a user, may return to a screen shown in FIG. 12B. The electronic device 101 may display service access control items 1219 and 1221 each of which indicates a user access status of each of the services 1215 and 1217 in the first device (e.g., SMART PHONE 1). For example, the service access control item 1219 associated with the first service 1215 (e.g., ChatON) indicates the “ON” state. This means that user account access to the first service 1215 (e.g., ChatON) is maintained. Also, the service access control item 1221 associated with the second service 1217 (e.g., S Health) indicates the “OFF” state. This means that user account access to the second service 1221 (e.g., S Health) is released. The electronic device 101 may receive an input event for the service access control item 1219 or 1221 from a user and transmit a control signal created in response to the input event to the device account server 108. Therefore, with regard to each individual service, a user of the electronic device 101 may control user access/release for services of the device stored in the device profile manager 180 b.

FIG. 12D is an exemplary diagram illustrating operations of, at an electronic device 101, controlling login/logout of a device or a service on the basis of proximity information with an external device according to an embodiment of the present invention.

According to an embodiment, at operation 1270, the authentication of a device or service may be finished in various embodiments discussed hereinbefore. For example, the authentication of the external device 107 or of a service offered through the external device 107 may be finished through the electronic device 101 and the device account server 108.

According to an embodiment, at operation 1290, the electronic device 101 or the device account server 108 may control login/logout of a device or service, based on proximity information between the electronic device 101 and the external device 107. For example, if authentication token information about the authenticated external device 107 or a service offered through the external device 107 is deleted or the available period thereof has expired, the electronic device 101 or the device account server 108 may support the authentication of the external device 107 or a service offered through the external device 107, based on proximity information with the external device 107. According to various embodiments, if a distance between the electronic device 101 and the external device 107 is equal to or smaller than a predetermined distance (namely, in case of proximity), the electronic device 101 or the device account server 108 may control the external device 107 or transmit a control signal to the external device 107 so that an automatic login is possible without any authentication process. Similarly, if a distance between the electronic device 101 and the external device 107 exceeds a predetermined distance, the electronic device 101 or the device account server 108 may control the external device 107 or transmit a control signal to the external device 107 so that an automatic logout is possible without any authentication process.

According to various embodiments, the external device 107 or a service offered through the external device 107 may be authenticated again (e.g., re-login) only after authentication approval through the electronic device 101 regardless of proximity information with the electronic device 101. For example, depending on attributes of the external device 107 or a service offered through the external device 107, it may be determined whether to perform authentication approval of the electronic device 101.

Meanwhile, as discussed earlier in FIG. 6C, the electronic device 101 may display, in the form of a popup UI having an OK button and a cancel button, the authentication request message 604 received from the device account server 108. The authentication request message 604 may include device information of the external device 107, service information, and a query about authentication approval. According to various embodiments, a display form of the authentication request message 604 is not limited to the above example. If security is required or if there is a user's demand, various authentication types may be further set.

FIG. 13A is a flow diagram illustrating a method of, at an electronic device 101, setting an authentication type for a device or a service according to an embodiment of the present invention. FIGS. 13B and 13C are exemplary diagrams illustrating operations shown in FIG. 13A. In the following description with reference to FIG. 13A, some operations similar to those of FIG. 6A may be omitted.

According to an embodiment, at operation 1310, the electronic device 101 may receive device profile manager information from the device account server 108. For example, in response to a user's request, the device account manager 125 may request the device account server 108 to offer information about at least one device and/or at least one service stored in the device profile manager 108 b.

According to an embodiment, the device account manager 125 may create a control screen for selecting of an authentication type in the electronic device 101, based on information of the device profile manager 108 b. In this process, the device account manager 125 may process information of the device profile manager 108 b received from the device account server 108. For example, it is possible to resort service information classified according to devices or device information classified according to services or to form such information by means of image items. Additionally, in order to allow a change in authentication type of the electronic device 101 for a device or service, the device account manager 125 may create a UI menu item or window for changing an authentication type.

For example, as shown in FIG. 13B, the electronic device may display registered device information 1301 and registered service information 1302 both of which have the form of a UI panel. The registered device information 1301 and the registered service information 1302 may be information stored in the device profile manager 108 b of the device account server 108. For example, the registered device information 1301 may contain a wearable device 1301 a, a smart printer 1301 b, and a smart TV 1301 c. For example, the registered service information 1302 may contain FACEBOOK™ 1302 a, NAVER™ 1302 b, and DAUM™ 1302 c. The illustrated classification form of the device information 1301 and the service information 1302 may be implemented at the device account server 108. Alternatively or additionally, the electronic device 101 may receive information of the device profile manager 108 b from the device account server 108 and classify the received information as shown in FIG. 13B.

Meanwhile, according to various embodiments of this disclosure, a plurality of authentication types shown in FIG. 13C may be predetermined by a user.

The electronic device 101 may receive in advance a user's input for selecting an authentication type needed to perform authentication for a device or service. For example, when any external device is registered in the electronic device 101 or in the device account server 108, an authentication type corresponding to the external device may be predetermined. Alternatively, when there is an authentication request from the device account server 108, at least one of authentication types registered in the electronic device 101 may be used in authentication for a corresponding external device.

For example, when a user selects the smart printer 1301 b as shown in FIG. 13B, the electronic device 101 may display a control window 1303 for setting an authentication type of the smart printer 1301 b as shown in FIG. 13C. In this case, displayed in the control window 1303 may be a list of authentication types registered in advance from a user. When a user selects one of authentication types displayed in the control window 1303 and enters preregistered authentication information, authentication approval is finished. For example, if a user selects a fingerprint type in the control window 1303, the electronic device 101 may further offer a suitable UI for receiving a user's fingerprint input and then determine whether the received fingerprint is matched to preregistered fingerprint. In case of matched fingerprint, the electronic device 101 may create authentication approval information for the printer 1301 b or for a service offered through the printer 1301 b.

According to an embodiment, at operation 1330, the electronic device 101 may set an authentication type corresponding to a device and/or a service. In this operation, the authentication type may be received from a user so as to create authentication approval information when an authentication request message is received from the device account server 108. The electronic device 101 may receive a user's input for selecting an authentication type.

Operation of receiving an input for selecting an authentication type may be performed in case an external device for authentication is a device requiring a security procedure in an access process or the like. Also, depending on types of external devices, a user may select whether to set an authentication type.

For example, when a user selects the smart printer 1301 b as shown in FIG. 13B, the electronic device 101 may display a control window 1303 for setting an authentication type of the smart printer 1301 b as shown in FIG. 13C. If a user selects a cancel button 1305, the electronic device 101 may display again a screen of FIG. 13C. If a user selects a password type as the authentication type of the smart printer 601 b through an authentication type window 1304 and then selects an OK button 1306, the electronic device 101 may store the selected authentication type in the memory 130. Thereafter, when a user authentication request message for a service of the printer 1301 b is received from the device account server 108, the electronic device 101 may create authentication approval information for the printer 1301 b or a service offered through the printer 1301 b in response to only a password input.

According to an embodiment, operations associated with setting, changing and deleting an authentication type may be performed at the electronic device 101 and, according to user's setting, may be also performed at the external device or the device account server 108.
